13 Claims.

My invention relates to improvements in the method of manufacturing loom'reeds.

Prior to my invention loom reeds have consisted of two different general classes, namely, (1) a pitch band or cotton and woolen reed and (2) an all metal or silk or rayon reed.

An object of my inventionois to provide a reed particularly suitable for weaving finer classes and grades of yarn, such as silk and rayon yam which will have all the advantages of an all metal reed and certain features of flexibility of the cotton or woolen reeds added thereto. Broadly speaking, my invention provides a loom reed comprising dents, means for rigidly securing the ends of said dents together at predetermined spaced in.- tervals and resilient dam means interposed between each dent inside of said rigid joining means near each end thereof instead of the customary wire springs employed in an all metal construction.

An object of my invention therefore is to provide a loom reed having the advantages of the rigid accurate spacings of the silk reed and in a measure the resiliency of the pitch reed.

A pitch band or cotton and woolen reed as it is called in the trade has for its composition, dents, complementally semi-circular wooden ribs placed on each side of the dents near each end thereof and pitched yarn wrapped around said wooden ribs to flexibly secure said dents together and end bars if desired. Standard types of machines have been developed for making these pitch band reeds, in which the dent wire is fed between the spaced wooden ribs cut to its proper length and a strand of pitch yarn is spirally wound around said ribs between each dent wire and so on until a given length of reed is made. The reed is then removed from the machine, the end bars fastened at each end and the reed then completed by hand.

The construction of an all metal reed is a much more complicated matter than the manufacture of a pitch band reed. First the dent wire is temporarily set between wooden ribs with plain untreated cord. The reed is next counted so that the correct number of dent wires is assured. The correct size of the spacing wire is then figured, which when coiled as a spring and placed in the reed between the dent wires will give the correct number of dents per inch and a spring is placed in the reed near each end of the dents and after the spring is inserted, the cord band is cut from the wooden ribs and the wooden ribs and cord are removed. Other temporary spacing springs are now placed onthe reed and moved to their respective places in the reed. Metal strips are now fixed to the sidesof the ends of the reed beyond said springs and a paste is applied to the spaces between the dents for the purpose of preventing the solder from running onto the metal surface of the dent wires through 5 said springs to the center portion thereof. Flat wooden boards may then be attached on each side of the reed with their ends terminating at the center portions of the wire springs to form a tight fit to prevent solder seeping around said wires. The metal reed is then dipped in solder. The reed is then washed in water and finally brushed to rid it of the paste and any traces of the acid soldering flux. This is very important in that any trace of acid which might remain on the dents will cause the wire to rust at thepoint where the spring comes in contact with it, which will eventually cause the wire to break at this point and ruin the reed.

My invention therefore 'is a novel method of manufacturing a novel type of reed generally similar to the old so-called metal reeds heretofore described.

An object of my invention is to interpose a permanent resilient dam means 'of a general type similar to the old pitch band in place of the wire spring to form the base of a solder well, the sides thereof being formed by the metal frame side bars affixed to each side of each dent near each end thereof. I have discovered that if this resilient dam means be made out of suitable material it will absolutely prevent the soldering acids or the solder from passing through it to the center portions of the dents and will thus eliminate. the expensive paste hitherto employed to prevent the solder and soldering acid from seeping through as in the former metallic springs of the so-called metal reeds. This resilient dam means performs a double function of acting as a dam to prevent the soldering acid or solder from seeping through in the manner hitherto described and also imparts the resiliency of the pitch band to this type of metallic frame to act as a buffer and to give more freedom of movement than the former rigid types of springs which were formerly rigidly soldered to the dents at the base of the solder wells and thus by interposing this resilient means between each dent, providing it with an additional resiliency hitherto unknown in the general type of all metal reeds. In place of the wooden bars of the usual pitch band reed, I substitute metal bars preferably half round-bars with their flat sides abutting the reeds which will not be aflected by the soldering heat. While pitch may be employed I have found in use and it will tend to run down or seep between the dents and harden and so for this purpose I preferably employ a substance which has an intrinsic capillary afllnity for theabsorbent cord when plastic so that as itis hardening it will be immediately attracted to the cord to harden even if it may melt somewhat and slip down the dents temporarily as the solder is employed and I preferably employ wax for this purpose.

An object of my invention therefore is: to provide not only a novel method of making a loom reed of the so-called all metal type in a simpler manner than heretofore, but also to make a loom reed ofthis description in which the dents are accurately spaced and which provides such a loom reed with some of the resiliency of the pitch band cotton or woolen reeds heretofore employed.

These and such other objects of my invention as may hereinafter appear will be best understood from a description of the accompanying drawings, which illustrate an embodiment thereof.

In the drawings, Fig. -1 is a diagrammatic view partially shown in section illustrating the method of impregnating my improved spacing cord with wax, a suitable acid-proof plasticizable material.

Fig. 2 is a side elevation of the initial step in the manufacture of my invention which consists in assembling the dents in reed form with the approximate desired spacings and winding the absorbent cords coiled around metal ribs on each side of said dents near each end thereof with a coil thereof interposed between each dent.

Fig. 3 is a side elevation illustrating the third step in my improved method which consists of temporarily spacing said dents to the desired spacings by interposing single winds of coil springs of predetermined size parallel to said wound cord between said dents to provide said desired spacings.

Fig. 4 is a side elevation of a partially formed reed in which the frame side bars have been temporarily secured to the dent ends by means of wireand the frame and bars temporarily secured to the ends of said reed by the temporary spring mounting bars.

Fig. 5 is a sectional view taken along the line 55 of Fig. 4.

Fig. 6 is a sectional view illustrating how each side end of my improved reed is dipped in a suitable solder bath and preferably raised to a horizontal position to permit the solder to become impregnated within the well thereof.

Fig. 7 is a perspective view of an improved reed constructed in accordance with my invention.

In the drawings, wherein like characters of reference indicate like parts throughout, l0 generally indicates a loom reed constructed in accordance with myinvention.

As shown in Fig. 7, said improved loom reed It comprises the usual spaced dents I2 provided with rigid means I4 securing the ends of said dents together and resilient dam means I 6 interposed between each dent inside of said rigid joining means l4 near each end thereof, the rigid means l4 comprising the frame side bars l8 and frame end bars 2i! rigidly soldered to each other by the solder '22 and to the ends 23 ofeach dent. It is thus apparent that in the finished product the rigid means l4 rigidly secures the ends of the dents together at the desired spaced intervals and that the resilient dam means l6 interposed between each dent'will provide a certypes of all metal reeds.

A further feature of my invention resides in the fact that the machines for making pitch .ber, rubber latex, certain synthetic or natural resins, tallow orother equivalent substances having these same general characteristics may be employed. If desired, however, pitch may be emtain resiliency in the. dents not common in former Y ployed, but I have found in use that this is not 20 so desirable as it does not when plastic have an intrinsic capillary amnity for the absorbent cord, but tends to remain between the dents when plastic and harden there. I have shown in Fig. 2 the initial step of manufacturing my improved reed in a standard type of pitch band reed making machine, in which the metal bars or strips, preferably half round or convexed'strips 30 with their fiat sides against the dents are substituted for the semi-cylindrical wooden bars employed therein and the wax covered cord 28 is substituted for the usual cord employed therein which may be impregnated with wax or equivalent dam material before or after its being helically wound around the bars 30 with a coil 32 thereof between each dent. It is obvious that the coils 32 between each dent particularly when covered with the wax cover 28 or other covering employed form the flexible resilient dam means l6 interposed between each dent to provide a certain degree of' resiliency therebetween. It is also obvious that in this step of the manufacture of reeds, the dents I2 are made in the usual reed setting machine which feeds the dent wires between the metal strips 38, cuts each dent wire l2 to the desired length, winds the strand of wax covered yarn so that a coil 32 thereof will be located between each dent wire and so on until a given length of reed is made and that in the usual manufacture on such a machine the dents l2 will be spaced from each other with the approximate desired spacings. If desired the wax covering 28 may be heated to I render it so plastic that it may readily wind during this operation.

I then temporarily space the dents l2 accurately to the desired spacings in the usual manner of making all metal reeds by figuring the correct size of the wire which would cause it to spring when placed on the reed between the dent wires to give the correct number of dents per inch and interpose coils 34 of such coiled wire 36 wrapped around the temporary metal bars 38 between said dents [2 to provide said desired spacings, said coiled wire 36 and side. 'bars 38 being interposed parallel to said wound cord 32 at spaced intervals across said dents as at .36 and 48, alternate coils being preferably of right and left hand pitch to accurately space the dents, the coils 36 being in terposed immediately adjacent the pitch or wax coils 28 parallel thereto and the coils 40 being conveniently placed substantially centrally of said dents and also parallel thereto. It is obvious, however, that the wax covering 28 of the cord 24 then being plasticized will prevent the dents from temporarily booming accurately spaced.

Then instead of the old process of making all metal reeds I do not remove the cord coil 24, but retain it as part of the finished reed, whereas in the all metal reed the cord coil would be removed and a metallic spring coil would form the base of the solder receptive well and as will be apparent in accordance with my method the spring coils 36 and 48 are merely temporary and will be removed in the finished article.

I then temporarily secure the metallic frame side bars l8 on each side of the ends of said dents beyond said dam means [6 to form solder receiv- .ing wells 42 (see Fig. 6) with said side plates l8 forming the side walls thereof and said dam means 16 forming the base thereof preferably being spaced somewhat from said side walls to permit the soldering acid to readily boil away therein and yet not spaced sufliciently to permit any substantial amount of solder to run out therebetween. As shown in Fig. 4 said metallic frame side bars I8 are temporarily secured on each side of the ends 23 of said dents beyond said dam means by the wires id.

Soldering acid is then applied in each well, such as hydrochloric acid, or other type of cleansing and soldering flux, such as now formed of an oil base containing the acid, or any other type of acid or flux employed. If desired the frame end bars 28 are inserted between the projecting ends of the bars 38 and bars 30 and secured thereto by wrapping one end of said bars around said end bars 20, as at 58 (Fig. 5), the portions of said end bars 20 near said dam means bars 38 being also suitably covered with suitable soldering acid or flux.

I then preferably secure by means of wires 41 the flat slabs 49, preferably wooden on each of said reeds so that the ends 5| will terminate at substantially the center portions of said dam means I 6 to prevent solder or soldering acid or flux from passing around said dam means It to the center portions of said dents. Each side end of said reed I8 is then successively dipped into the molten solder bath 46 up to the ends 5| of said wooden bars 49 and center portion of said dam means l2 to impregnate said well 42 with solder after which the reed I 8 may be raised to a position shown in full lines in Fig, 6 in a substantially horizontal plane to cause the solder 48 drawn in by said well to substantially fill said well, with said resilient coils 32 of said dam means I6 preventing the soldering acids or solder 48 from passing between the dents to attack the center portions of said dents and with the heat of the solder causing a temporary plastic condition of said plasticizable covering 28 to cause said spacing springs 38 and 40 to temporarily accurately space said dents during the simultaneous hardening of the solder to form with said side and end plates I8 and 20 rigid means ill to secure the ends 23 of said dents together at predetermined spaced intervals and to said end bars 20 and hardening of .said plasticizable acid proof covering 28 to a plasticized condition around said absorbent cord 24 to form resilient means interposed betweeneach dent inside of said rigid joining means. As stated hitherto, I preferably employ as a covering 28 for said cord 24, a plasticizable acid proof material having an intrinsic capillary aflinity for said absorbent cord when plastic and I have found that various types of waxes, such as paraffin wax, beeswax, rubber, certain resins, etc. have this highly desirable property. Pitch which I first tried does not, for while it functions admirably as a dam means to prevent the acid from attacking the center portion of the dents when heated by the solder it tends to run down the center portions of the dents and not having an intrinsic capillary affinity for the absorbent cord will tend to remain 5 and harden there thus making its removal necessary. It is obvious, however, that certain heavy oils, tallow, etc. not strictly plasticizable may be employed if desired.

I then remove the temporary spacing springs 10 36 and 40 with their respective metal bars 38 from the center portions of said dents, and remove the temporary holding wires 44 for the frame side bars and if desired may additionally solder the ends of the metal bars 30 to said frame 15 end bars 20. The dam means It may be covered with paper, if desired.

It is thus apparent that I have picked out the best parts of the former method for making pitch band cotton or woolen reeds and the method hith- 2o erto employed for making all metal reeds and combined them in a composite process for making a more efficient reed than any hitherto known. I have, however, as stated, modified the usual pitch band into a wax coveredband to preventitsrunning and hardening when plastic and substituted for the usual wooden side bars of the pitch band reed, the metal side bars which will not be aifected by the heat of soldering. While it is old to form a pitch band with wooden bars in the manufac- 30 ture of reeds I believe it is novel to employ wax bands with metal bars in the manufacture of reeds and not only employ them for their inherent purpose of adding resiliency to the reeds as employed in cotton or woolen reeds but also for the additional functionof providing a dam means to overcome the most basic fault in the manufacture of all-metal reeds, namely, the running of the acid and the solder to the center portions of the dents through the metal springs hitherto employed for this purpose, which in due course of time, if not completely removed, will corrode the dents. This also additionally eliminates in the manufacture of all-metal reeds the use of any of the objectionable paste hitherto thought necessary for this general purpose. It is also apparent that by my method I am enabled to provide a novel type of all-metal reed in which the dents are accurately spaced and in which they are provided in addition with the resilient means interposed between each dent inside of the the usual rigid joining means near each end thereof to give an added resiliency and flexibility to the dents, preventing the passage of weaving imperfections therethrough and in short provide a better type of all-metal reed manufactured with a lesser number of steps at a minimum cost than hitherto thought possible with this added functional characteristic of increased flexibility due to its inherent structure.

It is understood that my invention is not limited to the specific embodiments shown and that various deviations may be made therefrom without departing from the spirit and scope of the appended claims.
